The first oil well in North American is drilled.

The first oil well in North American is drilled in Lambton County, Ontario, in 1857/58. Although the oil field here is relatively small and nearly exhausted after a few years of production, it marks the beginning of Canada’s oil industry. The region, particularly around Sarnia, continues to be a major centre for petrochemical research and refinery operations.Source: Glenbow Archives, NA-302-9

Oil seeps in southern Alberta are documented.

George Mercer Dawson conducts numerous surveys of western Canada and its resources for the International Boundary Commission (1873-1874) and the Geological Survey of Canada (1875-1901). In 1874, he reports oil seeps in the Waterton area, 225 km (140 mi.) south of Calgary.Source: Glenbow Archives, NA-302-7

Petroleum is found in Alberta’s Turner Valley.

Control of natural resources is transferred to the provincial government.

The agreement transferring jurisdiction of natural resources from the federal to the provincial government is signed in Ottawa, December 14, 1929, and enacted the following year. (Seated, starting second from left, are Hon. Charles Stewart, Minister of the Interior and Mines; Rt. Hon. W. L. Mackenzie King, Prime Minster of Canada; and Hon. John Brownlee, Premier of Alberta.) The transfer allows Alberta to realize the full economic potential of the oil and gas resources found within its borders. Source: Provincial Archives of Alberta, A1092

Leduc No. 1 sets off the modern oil sector in Alberta.

Imperial Leduc No. 1 blows in, setting off the modern oil sector in Alberta. The discovery of the Leduc oil field, then the largest and most lucrative yet found, comes after decades of fruitless searching and drilling. It marks the beginning of Alberta’s modern oil industry and completely revolutionizes the province’s economy and prospects. Source: Provincial Archives of Alberta, P1342

Additional oil discoveries confirm Alberta as a major oil producer.

Oil derricks dot the landscape, and smoke from a new oil well rises from the horizon beyond the hamlet of Redwater. On the heels of the Leduc discovery, Imperial Oil finds a second major oil field near Redwater, northeast of Edmonton. Larger and easier to access than Leduc, this discovery confirms Alberta’s future as a major oil producer. Source: Provincial Archives of Alberta, A9763

The Interprovincial Pipeline expands the market for Alberta’s oil.

Completed between Edmonton, Alberta, and Superior, Wisconsin, in 1950, the Interprovincial Pipeline is a vital transportation link that makes Alberta’s oilfields financially viable. By 1956, the pipeline is expanded and extended to Sarnia, Ontario, and is transporting more than 200,000 barrels a day.

“Fracking” opens up previously inaccessible oil reservoirs.

A wellsite geologist stands in front of the Pembina No. 1 oil well. A joint venture of two oil companies, this well successfully strikes oil about 100 km (62 mi.) southwest of Edmonton. The oil at Pembina is accessed by a developing technology called sandstone fracturing or “fracking.” This technology makes it possible to extract previously inaccessible oil reserves and becomes more widely used throughout Alberta in the following decades.Source: Glenbow Archives, NA-5103-9

Oil is discovered in Alberta’s remote northwest.

In 1965, the Banff Oil Company drills successful wells in this region. They are the first major oil discoveries in this remote area of Alberta’s northwest. Source: Glenbow Archives, S-236-46

The OPEC oil embargo rocks energy markets.

Starting in 1973, the Organization of Petroleum Exporting Countries (OPEC) begins restricting oil exports to much of the Western world, including Canada. Fuel shortages become common, and the price of Alberta oil, one of the few remaining reliable and friendly sources of oil for industrialized nations, skyrockets.

West Pembina injects new life into Alberta’s oil sector.

The NEP alienates Alberta’s oil patch.

The National Energy Program is created by the federal government in 1980 to ensure a reliable and affordable supply of oil and gas for Canadian industry. The provincial government perceives it as an unwarranted intrusion into its affairs and as sacrificing Alberta’s interests in favour of those of Central Canada. Although a compromise is reached in 1981, bitter memories of the NEP continue to characterize Alberta-Central Canada relations. Source: CP Photo/Dave Bunston, 03263367

The Western Accord brings NEP regulation to an end.

Within a year of this meeting, the Governments of Alberta, British Columbia and Saskatchewan will negotiate the Western Accord, which ends the National Energy Program, deregulates oil prices and encourages new investment in western Canada’s oil sector. Source: CP Photo/Pat Price, 673836

Environmental concerns challenge the practices of the petroleum industry

Images such as these feed concerns through the Western world about environmental damage due to industrial development. In 1987, the United Nations World Commission on Environment and Development releases the report Our Common Future. It encourages the concept of “sustainable development” in an attempt to balance First World concerns about human rights and environmental degradation with Third World nations’ need for economic development. Although not directly related to the oil sector, this concept forms the basis for future anti-pollution and climate change strategies. Source: Glenbow Archives, NA-2864-20312

Oil Developments After Leduc

The 1947 discovery of oil at Leduc ushered in a twenty-year period of intense exploration, new discoveries and expansion of Alberta’s oil industry. Scientists began to look more closely at the Devonian reef formation in which the Leduc oil had been found. The reef had been formed during the Devonian period, between 418 and 355 million years ago. It is known as the “Age of Fishes” due to the great proliferation of fish species that thrived during that period. Giant marine reefs grew in the tropical sea that covered the area that would become Alberta.

In 1948, Imperial Oil found another Devonian reef formation near the hamlet of Redwater, 64 km (40 mi.) northeast of Edmonton. The Redwater reserves were shallower than those at Leduc and produced more oil. The field was eventually determined to be 32 km (20 mi.) long and 6½ km (4 mi.) wide, and was supporting 926 wells by 1953 and producing almost 30% of the province’s output. The large volume of crude being produced made the construction of large transmission pipelines essential.
